Ahead of the Iowa Caucus on Feb. 1, presidential candidates on both sides are making their presences very much felt in the state. Vermont Sen. Bernie Sanders intends to win over more voters at a rally in Iowa City on Saturday (Jan. 30) with the help of a few key musical guests.

The rally comes right on the heels of Rostam Batmanglij’s announcement yesterday that he has parted ways with Vampire Weekend. It’s unclear whether or not he’ll be present for the band’s performance this weekend. (Just before announcing his departure from Vampire Weekend, Batmanglij expressed his support for Sanders.) The Sanders rally also marks Vampire Weekend’s first live gig since 2014.

Killer Mike has been an outspoken supporter of Sanders. The Run the Jewels rapper introduced Sanders at a rally in his hometown of Atlanta back in November. (They also had lunch together, which can be seen in the photo below.) Killer Mike then spoke with the presidential hopeful in a six-part interview that took place at his Atlanta barbershop. The conversation covered theeconomy, social justice, health care, political protests and voting.
